The steps in manual (non-automatic) machine vibration analysis are:
Identifying vibration peaks in the spectrum and relating them to forcing frequencies
Determining the severity of machine problems from the amplitudes and relationships between the vibration peaks.
Making the appropriate repair recommendations based on the severity of the machine problem.
In order to do a proper job of vibration analysis, several tools are needed: If the vibration spectra are being analyzed on a computer, a calculator and Vibration Test and Analysis Guide (VTAG) for the machine in question are required. If the vibration spectra have been printed on paper, then a straight edge and ten-point divider are desirable. Previous vibration data and average vibration data are also helpful if available.
